A flasher targeting a series of Northeast Portland neighborhoods struck again Thursday when he exposed himself to a child at Northeast 30th Avenue and Mason Street.

The man -- described as between 20 to 40 years old, and 5 feet 9 inches to 6 feet tall – ran away, the Portland Police Bureau reported. Police were not notified of the 4:30 p.m. incident until about 5 p.m. and were unable to find the suspect.

Residents, police said, are on alert and authorities were called to the 1800 block of Northeast 33rd Avenue Friday morning to check out a report of a man removing clothes on the corner.

Ten police officers raced to the scene.

But it turned out the man was taking off an outer layer of rain gear before getting on a bus.

Police have released a forensic sketch of a suspect, who has been known to cover his face, police said.

The man is 170 to 185 pounds, medium to heavy build with dark brown hair. He has been described as both clean-shaven, and having a scruffy face. He’s been seen wearing a white t-shirt, dark-colored boxer shorts, and dirty old running shoes.

In one incident, a possible suspect vehicle was reported to be a gray to gold to brown larger American sedan.

Police are providing extra patrols in the neighborhoods, and the bureau’s sex offender registration detail is reviewing files to see if any registered sex offenders match the suspect description and activity.

Area residents are asked to be vigilant and report any suspicious activity immediately.

Police said if any residents in the area of this incident have residential surveillance cameras, investigators are asking them to check recordings for any possible images of the suspect.

Anyone seeing this suspect or encountering him is asked to immediately call 9-1-1. Anyone with non-emergency information should call 503 823-3333.
